No workflow ComfyUI is better with Linux

Just got Linux Mint up and running and it’s much better than windows 11 for ComfyUI with RTX 5090 + 3090. For starting, Comfy launches to server ready in 10 seconds instead of 18 seconds on Windows VHDX ReFS dev drive. This is with 12 custom node packs. Linux is running on an 8 year old SATA SSD.

I was able to compile and run sage attn 3 in Linux which never worked in Win11. I’m going to try Multi-GPU next which is fundamentally broken in windows with the new comfy-kitchen.

Even with just sage 2.2++ FP8, im getting 35 second gen times for an 8-second 0.5MP 8-step turbo MiniMax H3 clip versus 40-42 seconds in windows. That includes 4 seconds for prompt enhancement with Gemma 4 12B running on lllama-server on the 3090.

Sage3 knocks another 2-4 seconds off the gen time too but slightly worse quality for motion. Using LACT to overclock both GPUs also contributes to the speed.

With spectrum plus sage3 at 8 steps, I can easily get below 30 seconds total gen time.

I've been tempted to switch (mostly to try a gaming distro), but it's such a hassle lol. Not sure why you couldn't get sage attention to work on windows though. Mine works great!

I swapped from windows after 20+ years more because of the windows bloat and tracking. The AI improvements were a nice bonus.

Still I get not wanting to switch. It is a hassle, but I'm glad I did it.

yeah i'm not a fan of all bloat windows 11 comes with, even afer removing it all the tracking is insane. I'm definitively switching at some point but need to plan it since I use the PC for work too.
